It’s a visibility modifier—it means that instance variables declared as @private can only be accessed by instances of the same class. Private members cannot be accessed by subclasses or other classes. For example: @interface MyClass : NSObject { @private int someVar; // Can only be accessed by instances of MyClass @public int aPublicVar; // Can … Read more
No. You can fork it and it still remains private. Private collaborators may fork any private repository you’ve added them to without their own paid plan. Their forks do not count against your private repository quota. https://github.com/plans
Most of the confusion in the question/answers here surrounds the definition of Inheritance. Obviously, as @DigitalRoss explains an OBJECT of a subclass must contain its superclass’s private fields. As he states, having no access to a private member doesn’t mean its not there. However. This is different than the notion of inheritance for a class. … Read more
In Python, “privacy” depends on “consenting adults’” levels of agreement – you can’t force it (any more than you can in real life;-). A single leading underscore means you’re not supposed to access it “from the outside” — two leading underscores (w/o trailing underscores) carry the message even more forcefully… but, in the end, it … Read more
In general, static means “associated with the type itself, rather than an instance of the type.” That means you can reference a static variable without having ever created an instances of the type, and any code referring to the variable is referring to the exact same data. Compare this with an instance variable: in that … Read more
Private members are only accessible within the class defining them. Protected members are accessible in the class that defines them and in classes that inherit from that class. Edit: Both are also accessible by friends of their class, and in the case of protected members, by friends of their derived classes. Edit 2: Use whatever … Read more
internal is for assembly scope (i.e. only accessible from code in the same .exe or .dll) private is for class scope (i.e. accessible only from code in the same class).
If you want to unit test a private method, something may be wrong. Unit tests are (generally speaking) meant to test the interface of a class, meaning its public (and protected) methods. You can of course “hack” a solution to this (even if just by making the methods public), but you may also want to … Read more
Assuming no SecurityManager is preventing you from doing this, you can use setAccessible to get around private and resetting the modifier to get rid of final, and actually modify a private static final field. Here’s an example: import java.lang.reflect.*; public class EverythingIsTrue { static void setFinalStatic(Field field, Object newValue) throws Exception { field.setAccessible(true); Field modifiersField … Read more
In order to access private fields, you need to get them from the class’s declared fields and then make them accessible: Field f = obj.getClass().getDeclaredField(“stuffIWant”); //NoSuchFieldException f.setAccessible(true); Hashtable iWantThis = (Hashtable) f.get(obj); //IllegalAccessException EDIT: as has been commented by aperkins, both accessing the field, setting it as accessible and retrieving the value can throw Exceptions, … Read more
